LAP infrastructure
LAP Infrastructure
At the Laboratory of Atmospheric Physics (LAP), systematic measurements of solar radiation and atmospheric constituents are routinely performed using both active and passive remote sensing techniques. The first measurements of total ozone by UV spectroscopy began in 1982, and since then LAP has developed and/or procured scientific equipment of the highest standards, as they are defined by International Organizations and Networks. The LAP monitoring station and its routine atmospheric observations are integrated into the Global Atmosphere Watch of the World Meteorological Organization (GAW/WMO), the Network for the Detection of Atmospheric Composition Change (NDACC), the European Brewer Spectrophotometer Measurement Network (EUBREWNET) and the European Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS), to which LAP is participating as an official national infrastructure station, part of the PANACEA network (https://panacea-ri.gr/).
